CHARLES E. SMITH, OF LOWELL, MASSACHUSETTS.

IMPROVEMENT IN LOOM-PICKINQMECHANISMS.

Specification forming part of Letters Patent No. 133,493, dated November26, 1872.

To all whom it may concern:

Be it known that I, CHARLES E. SMITH, of Lowe1l,in the county ofMiddlesex and in the State of Massachusetts, have invented certain newand useful Improvements in Looms; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon making part of this specification.

Thenature of my invention consists in the construction and arrangementof certain devices for operating the picker-staffs for throwing theshuttle in looms, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, 'referrin g to the annexed drawing, in whichFigure l is a perspective view of so much of a loom as will illustratemy invention, and Fig. 2 represents detached parts of the same.

A represents a horizontal shaft, upon which are secured two cams, B B,for alternately operating the levers (J C. These levers are placedhorizontally, each being pivoted at one end to a cross-bar in the frameof the loom, and at or near its center provided with an arm, a, to theouter end of which a friction-roller, b, is affixed, against whichroller the cam works. The lever is pressed inward against the cam bymeans of a spiral spring, (1, one end of which is placed in a socket, 0,attached to the lever, and the other end placed around a screw, f,fastened to the frame of the loom. On this screw is a nut, h, againstwhich the end of the springd bears, and which nut may be moved out or inon the screw, as desired, to regulate the tension of the spring, therebygiving more or less power for operating the picker-staffs, as occasionmay require. The outer ends of the levers (J (J are connected with thepicker-staffs D D by means of adjustable rods m m, or rods that may belengthened or shortened at will, thereby giving more or less throw tothe statfs, as may be desired.

By the operation of these devices the shut- .tle is thrown with equalvelocity, however slow or fast the other parts of the loom may bemoving,

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In combination with the levers for operating the picker-staffs oflooms, the adjustable springs d d, sockets e 6, screws ff, and nuts h h,all substantially as and for the purposes herein set forth.

2. The combination of the cams B B, levers O O with arms a andfriction-rollers b 11, adjustable springs d d, adjustable connectingrodsm m, and picker-staffs D D, all constructed substantially as and for thepurposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this13th day of Witnesses:

J. S. WHITNEY, F. E. ROLLINS.
